Example #2

void UpdateCamera(float elapsedTimeSec)
{
    Mouse &mouse = Mouse::instance();
    float dx = -mouse.xPosRelative();
    float dy = -mouse.yPosRelative();

    g_camera.rotateSmoothly(dx, dy, 0.0f);
    g_camera.updatePosition(GetMovementDirection(), elapsedTimeSec);

    mouse.setPosition(g_windowWidth / 2, g_windowHeight / 2);
